When Diddy hosts anything, you know it’s going to be a "movie."

Last night, the Hip Hop mogul called upon his friend Naomi Campbell to help his host a special screening of his upcoming documentary Can’t Stop, Won’t Stop: A Bad Boy Story’ at the Curzon in Mayfair.

Can’t Stop Won’t Stop: A Bad Boy Story (produced by Sean “Diddy” Combs, and Heather Parry, alongside executive producers Michael Rapino, Andre Harrell and Alex Avant) gives viewers a look behind the scenes at the history of Bad Boy through a complex portrait of the label’s mastermind (Diddy) as he tries to reunite his Bad Boy Family in the course of a frantic three week rehearsal period.

Following the preview, the Bad Boy honcho and the supermodel co-hosted an exclusive dinner at Loulou’s where guests dined on smoked salmon followed by roast poussin, wild mushrooms and Madeira sauce, with apple sorbet, fruit salad and chocolate for dessert. Yummy. As expected, there was an unlimited supply of Diddy’s DeLeón Tequila and CÎROC Driver cocktails.

Before heading inside, the Hip Hop mogul, who landed in the No. 1 spot on Forbes’ list of Hip Hop’s Wealthiest Artists, stopped to snap selfies with fans.

Diddy’s longtime girlfriend Cassie came along for support. Of course. She styled in a printed Maje jumpsuit and Balenciaga heels.

The runway slayer worked this Alexander McQueen ensemble from the brand’s 2217 RTW collection. She topped her look off with a cropped bob.

Lupita Nyong’o was also on the scene working a Fendi ensemble from the Fall 2017 collection. The Oscar winner will return to the big screen when Stars Wars: The Last Jedi hits theaters December 15th.

The YBF starlet ran into actress Salma Hayek, rocking Gucci threads, and had to get her selfie session.

There were more models in the building…

Jourdan Dunn and Winnie Harlow snapped it up with singer Tinashe during the festivities. Fun times.

Can’t Stop Won’t Stop: A Bad Boy Story will premiere exclusively on Apple Music on June 25th.

At another event…

Simple, yet elegant.

Singer Jhene Aiko put her fashion foot forward in a Jill Stuart ensemble paired with Prada shoes and a Dior bag to kick off the Billboard Music Awards festivities at the Women in Music event held at At YouTube Space LA.

We need that clutch!
